I'm guessing this has something to do in relation with the glamour change, but you can't seem to change gear on the fly in dungeons like you used to.

Example being I just hit level 35 on AST in Sastasha and now I can't upgrade to wear my level 35 armor. I have to walk out and do it? Shame. That gear could have given me more MP! (all joking aside it is lame)

It says that I can't change classes or jobs at this time, but that's not what I am doing. Could be a bug? I don't know.
